Build GTK 4 binaries

Currently the GTK4 binaries are not build as part of the build, this has
several drawbacks:

1) If anything is adjusted for GTK4 part it might break without notice
2) We have no GTK4 binaries by default

This enables *compilation* of the gtk4 parts to see at least everything
can be compiled.
